Homework Statement
If you increase the charge on a parallel plate capacitor from 3μC to 9μC and increase the plate separation from 1mm to 3mm, the energy stored in the capacitor changes by a factor of...
Homework Equations
U = 1/2QV
or 1/2CV^2
The Attempt at a Solution
I'm not sure which equation to even use, I'm not to great when it comes to differentiating between electric field and energy of the capacitor.
I think I should probably use 1/2QV but i don't have a voltage to work with so I'm confused.
